Question

the sun angular diameter is 30''the distance of earth from sun is 1.496 x 10¹¹m.find the diameter of the sun​

Answer 1

Answer:

The sun's angular diameter is measured to be 1920

Answer 2

Answer:

The Sun's angular diameter is measured to be 1920".

Distance of the sun from the earth, S= 1.5 × 10¹¹m.

Angular Diameter of the sun, = ø(theta) = 1920''=1920×4.85×10^-6 rad

Linear Diameter of the sun, =

D=S×ø= 1.5×10^11×1920×4.85×10^-6

So, Diameter = 1.4×10^9 (ans)
